I saw that you asked us to ignore your support ticket with the same text, but I will answer anyway, in case someone else has the same question:
1) The "Please wait" box is a simple panel, that contains custom animation. It is just displayed when there is a time consuming operation currently in progress. The examples for each control are in different XAP files and we display the box while we are downloading the XAP.
2) The animations while changing the examples and while switching to view code are custom transitions for RadNavigation. We can provide more information about how to achieve it if you decide to use it.
We plan to publicly release the source code of our examples' framework, the so called QuickStart, in the near future, most probably near the Q3 release, in the beginning of the winter.
